AP CSA Unit 2 Day 8: Iteration For Loop Count

February 6, 2026

Unit 2, Selection & Iteration • Cycle 2

Day 8 Advanced Practice • Harder Difficulty

Focus: Loop Iteration Count Hard Iteration (for-loop count)

Advanced Practice Question

Format: Iteration (for-loop count)

What is printed?

int count = 0;
for (int i = 0; i < 5; i++) {
    count++;
}
System.out.println(count);

Difficulty: Hard | Topic: Iteration (for-loop count) | Cycle: 2 (Advanced)

Why This Answer?

`i` takes values 0, 3, 6, 9 (four iterations). Each iteration increments `count`, so it prints 4.

Common Mistake

Watch Out!

Stopping at `i = 6` and forgetting `i = 9` still satisfies `i < 10`.

AP Exam Strategy

List the actual `i` values the loop uses; don't guess.

This Cycle 2 HARD question tests loop iteration count. Review Unit 2 concepts to build mastery of selection and iteration.
